Arkham Horror LCG Mythos Pack : Undimensioned and Unseen

Things are definitely getting weird in Undimensioned and Unseen, the fourth Mythos Pack in The Dunwich Legacy cycle for Arkham Horror: The Card Game.

A mystery within a mystery, Undimensioned and Unseen may bring you another step closer to your ultimate goal, but you must first track down whatever knowledge or power may allow you to defeat a number of otherwise invulnerable Abominations.
